LWRC International continues to deliver the goods, especially with this SPR model! This Land Warfare Resources Corporation International IC-SPR rifle employs the low-profile fixed gas block for the short-stroke piston system. This non-adjustable piston system is one of the most reliable systems on the planet. This rifle features a 16-inch spiral-fluted cold hammer forged barrel for incredible strength and durability, even during sustained firing strings. In addition to the monoforge upper receiver and the LWRC modular free-float handguard you will receive the LWRC adjustable compact stock. Additionally, it’s worth noting that the rifle ships standard with the skirmish sights so that you can get up and running right out of the box.
